What's New is an index, not a publisher: every entry below links to the vendor's own release notes, which are the authoritative source. Entries are labelled where they are hand-curated sample data, pre-releases, or drawn from a secondary source such as a developer blog.

Reuse: the summaries, labels and curation here are © What's New. Quote freely with attribution and a link back; wholesale republication of the corpus is not permitted — terms: https://whatsnew.fyi/terms. The vendors' own release notes remain their publishers'.

- **changed** — Done transitions now receive `output` directly in callback arguments for XState done events

###### Patch Changes

-   667d1c7: Done transitions now receive `output` directly in callback arguments.

    ```ts
    invoke: {
      src: fetchUser,
      onDone: ({ output }) => {
        output.name;
      }
    }
    ```

    The direct `output` value is only provided for XState done events, such as
    `xstate.done.actor.*` and `xstate.done.state.*`.
